Review Questions

• How does rack focus enhance the emotional impact of a scene?
  • Rack focus enhances emotional impact by directing the viewer's attention intentionally from one subject to another, creating a visual narrative that mirrors the story's emotional dynamics. For instance, shifting focus from a character in despair to a symbol of hope can evoke deeper feelings and highlight critical relationships. This technique allows filmmakers to manipulate audience perception and engagement, making emotional moments more resonant.
• In what ways does the choice of lens affect the execution of rack focus?
  • The choice of lens significantly affects how rack focus is executed and perceived. A wide-angle lens tends to create more dramatic shifts due to its exaggerated depth of field, while a telephoto lens offers a shallower depth of field that may require more precision. Each lens type brings its own aesthetic qualities; for example, rack focusing with a macro lens can create an intense close-up effect that heightens intimacy. Understanding these differences allows filmmakers to choose the appropriate lens based on the desired emotional or narrative outcome.
